Ceramic Coated Headers for GM LS Trucks & SUVs 2002-2013
Ceramic Coated Exhaust Headers for 2002–2013 GM LS Trucks & SUVs | 1-5/8" Primaries
Product Description
Upgrade compatible 2002–2013 GM LS-powered trucks and SUVs with Certified Automotive Experts Ceramic Coated Exhaust Headers. Designed to replace restrictive factory cast-iron exhaust manifolds, these headers feature 304 stainless steel construction, 1-5/8-inch mandrel-bent primary tubes, and a high-temperature ceramic coating.
Precision TIG-welded seams and 3/8-inch-thick laser-cut flanges provide durable construction. The ceramic coating helps manage exhaust heat and protect against surface corrosion, making these headers suitable for compatible daily drivers, work trucks, towing vehicles, and LS performance builds.
Important: The passenger-side outlet uses a ball-and-socket beveled flange designed for factory Y-pipes with a donut-style gasket. Vehicles with a flat passenger-side flange are not compatible. Verify your vehicle's configuration before ordering.

Fitment Reminder
Before ordering, verify your vehicle's model year, engine and cylinder-head configuration, and factory exhaust connection. Pay particular attention to the passenger-side Y-pipe flange: the required connection is a ball-and-socket beveled flange using a donut-style gasket, not a flat flange.
